<em>"Of the following dotplots, which best represents the possible results from the simulation described?"</em>
The sample size is 100, and the probability of success is 0.015, so the expected value is 1.5. Meaning we would expect a dotplot with most of the dots at 1 and 2.
The numerical expression would be
[One] - [minus] [the product of]
, [unknown number].
is the product of 4 and x
First, graph the "equals" line, then shade in the correct area.
There are three steps:
1) Rearrange the equation so "y" is on the left and everything else on the right.
2) Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)
3) Shade above the line for a "greater than" (y> or y≥)
or below the line for a "less than" (y< or y≤).
